Be it known that I, ANGELO siding at Wilmington, Delaware, haveiinvented1 certain new and useful Improvements in Locks, of which the followingis a specification.

My present invention relates to improvements in-permutation locks andaims to provide a simple, economical and durable construction in whichthe combination may be readily varied.

With these and other objects in view the invention includes the novelfeatures of construction and arrangement and combination of partshereinafter described and particularlydefined by the appended'claims- Mypreferred embodiment of my invention is illustrated in the accompanyingdrawing in which:

Figure 1 is a plan view of my improved lock with thecover removed.

Fig. 2 is a plan view showing the cover.

Fig. 3 is a perspective view of the lock frame or case.

Fig. 4: is an edge view of lock frame looking from the left of Fig. 1.

Fig. 5 is a'perspective view of the looking bar of member. 4 V

Fig; 6 is a perspective View of-the push means for operating'the lockingmember.

Fig. 7 is a detailed side elevation of one of the shafts.

Fig. 8 is a sectional detail of one of the locking disks, and,

Fig. 9 is a perspective view of the keeper.

Referring by reference characters to this drawing the numeral 1designates the main frame or case of the lock which may comprise a barof metal bent to the shape clearly shown in Fig. 3 with the ends spacedapart to form a keeper receiving opening 1*. Cover plates 2 are securedto the top andbottom of this frame to complete the lock casing, by anysuitable means, such as screws, and I prefer to form at least one ofthese, of two sections, one being permanently secured to the frame andthe other hinged to the former, thereby preventing any danger of loss ofparts of the casin when the same is opened to change the com ination. Ifthe lock is to be engaged by the keeper by a relative movementtransverse to the plane of the lock casing, the cover plates areprovided with cut away portions2 corresponding in size and shape to thekeeper 3 which has an eye 3 designed to be engaged by the Specificationof Letters Patent.

' Application filed November 16, 1918. Serial No. 262,830.

angularly turned end 4* of the slidable member or looking bar .4.This'bar is provided-with a plurality of holes 4 through which pass acorresponding number of shafts 5 which are journaled in the walls of thecasing and project therethrough at one end where they are provided withheads 6 bearing permutation characters.

Each shaft 5 has an annular groove 5 and a longitudinal groove 5communicating therewith. On each shaft in line with the annular grooveis loosely mounted a disk or ring 7 provided with a plurality of radialscrew holes corresponding in number and position to the characters onthe corresponding head-6, and a screw 7 is designed to be insertedthrough any one of these holes and have its inner end engage the annulargroove. It will readily be seen that these screws prevent the disks orrings from being moved to the left (Fig. 1) until the shafts have beenturned to cause the longitudinal grooves to aline with the ends of thescrews. The disks or rings are prevented from turning with the shafts byprojections 7 thereon which engage corresponding recesses 4 in thelocking bar.

A spring 8, encircling one of the shafts,

' normally keeps the locking bar pressed into locking position.

In order to move the locking bar to the left, (Fig. 1) to unlock orrelease the keeper when the shafts have all been turned to properposition I provide a ush plate 9 having holes by which it is sli ablymounted on the shafts, and this plate is provided with a push rod 10extending outside the casing, this push rod being conveniently madetubular and slidably mounted on the outer portion 5 of the intermediateshaft 5.

It will be understood that the case or frame is provided with suitableindicating marks as shown by the arrow heads, Fig. 4, to indicate wherethe permutation characters are to be positioned to set the lock inunlocking position, and that the disks or rings 7 are provided withpermutation characters corresponding to the characters of the heads 6 toaid in initially setting or chang ing the combination.

Having thus described my invention, what I claim is 1. In combination, acasing having an opening in one wall, a keeper having an eye adapted toenter said opening, a spring pressed bar mounted to move transversely Vrality of parallel 'shaiftsl journale'd inthe casing and having heads onthe outside of of said opening and having a portion adapt ed to engagethe eye of the keeper, a pluthe casin said shafts passing :throughopenings in said slidable member, disks loosely mounted on said shafts,means fonholding-the disks against rotation, means for holding saiddisks; against longitudinal movement ionv the shaftsexceptwhenzthetlatter are in -a :predetermined position and; means for movingthe disks, bodily y when in such position.

2. In combination, ,a casing .=having an opening in one wall, a keeperhaving an eye adapted to enter said opening, ,a spring pressed bar,mounted to move transversely of said opening and having a portionadaptedto engage the eye of the keeper, a plurality of parallel shafts journaled in the casing and having heads on the outside of the casingbearing permutation characters, said shafts )assimrthrou h o eni-n 's insaid-slidable memberland having each airannula-r groove and alongitudinal groove-terminating in the-annular groove, disks looselymounted on said shafts, each having aprojection to coact withsaidkgrooves, means at for holding said :disks against rotation, and, apush member for-acting on said disks.
